When a Bomb Gem reaches zero, a klaxon sounds, the screen zooms in to the Bomb Gem, and the Disarm Spinner activates. There are eight gems on the spinner, two of which will change to skull symbols. The spinner then spins, and the player may click the stop button to stop the spinner. If the spinner stops on the skull icons, the game is over. If the spinner stops on a pair of gems, the game continues. You will then be returned to the gem board and 6 twists will be added to any other Bomb Gems on the board.
Each time a Bomb Gem counts down to zero, the Disarm Spinner is activated with another two gems replaced with skull icons. This means that the first time you encounter the Disarm Spinner, you have a 3 in 4 chance of continuing your game; the second time a 2 in 4 chance; and the third time a 1 in 4 chance. After 3 Bomb Gems have counted down and activated the Disarm Spinner, any additional use of the Disarm Spinner will give you a 1 in 4 chance of continuing your game.
The Disarm Spinner only appears in Classic mode. In Blitz mode, though, because in Blitz if a bomb reaches zero, it will immediately explode, and the game ends.
